ADVERTISING DEVICE.

Application filed May 19, 1924'. Serial No. 714,191.

provements in AdvertisingDevices, o'twhich the following is a specification.

The presentinvention relates to advertising devices; and its object is to provide an improved device of that cl'iaracter, adapted to display a succession of advertising matvter, and operated by the opening or closing movement of a door. 7 v v This and any other Ob ects hereinafter appearing are attained by, and the invention finds preferable embodiment in, the structure hereinafter particularly described in the body of this specification and illustrated by the accompanyingdrawings, in which Figure l'is aface view of a portion of a door swingably mounted on itsdoor jamb, the doorand jamb carrying my advertising device;

Figure 2 is a topplan view of said device, the door and jambjbeing sectioned horizontally on line 22 of Figure 1:

Figure 3 is a central longitudinal sectional I ,ure 7. The oppositely-disposed helical porview of a portion of said device, enlarged;

Figure 4t is a development of a portion of the cam bearing of said device, showing the rcciprocative element whereby the display element is rotated;

Figure 5 is a transverse sectional view of the display element of the device, taken on line 55 of Figure 3;

Figure 6 is a transverse sectional view of a fragment of said display element taken on line 66 of Figure 3; and

Figure 7 is a top plan view of the device, showing the position of certain parts in the partially open position of the door.

My advertising device is shown mounted on the inner side of a door 1 swingably mounted by its hinges 2 on its jamb 3, and having a glazed portion 4 through which the advertising matter displayed by the de vice, as on the cards 5, may be seen from outside the door, a portion of the device however being carried by the door jamb 3. A display element 6, which may be formed of metal plates 'Twelded or soldered together adjacent their edges as seen in Figure 5, has longitudinally extending grooves 8 adapted to slidably receive the cards 5 displaying the advertisements. This display element may be provided with a casing 9, and is rotatably mounted in bearings 10 on brackets or casing ends 11 secured to the inner side of the door as by screws 12; An extension 13 of this display element, concentric with its journals 1% has in its curved side a groove or cam bearing, designated generally 15, comprising a connected succession of alternately oppositely-disposed helical portions 16, 1'? of helically high pitch. The display element 6 is given successive partial rotative movements in the Same direction by, successive swinging movements of the door, by the following mechanism: an element 18 having a reciprocatingmovement in a bearing 19 on i the. door, has a laterally extending lug 20 engaging in the cam bearing This element 18 1s reciprocated by the swinging of the .door by connections between said element andithe door jamb, such connections'in the construction shown comprising a lever 21 fulcrumed at 22 on the door and connected,

with the reciprocating element, preferably yieldingly as by the coiled spring 23. This lever is, pivotally connected at 241 to a leaf spring 25 mounted at 26 on the door jamb 3 and adapted to be flexed by the swinging movement. of the door, as indicated in Fig tions 16, 17 of the cam bearing have adjacent theirmeeting points, guiding extensions 27, so thatin the rotationof the display element the lug 20 of the reciprocating element may be guided from one of said portions into the succeeding oppositely-disposed portion of the cam bearing instead of returning in the preceding portion and thus rotating the display element reversely.

It will be seen from the above description of the parts of my device, that each successive closing and opening movement of the door flexes the leaf spring 25 With it, which spring is sufliciently rigid vertically and longitudinally to swing the lever 21 and thus reciprocate the element 18 whose lug 20 traveling from one portion 16 or 17 of the cam bearing to the oppositely-disposed portion 17 or 16 thereof, imparts a partial rotation to the display member 6, and thus displays through. the glazed portion 4: of the door, the cards 5 in succession; and that the coiled spring 23 cushions the action of the reciprocating member 18.

Instead of the leverswinging member being in the form of a spring 25 as shown in Figure 7, it may take the form of a bar 25 swingably mounted hingedly at 30 on the jamb (i. e., on the bars extension 25 secured at 26 to the jamb) and connected at 24 to the lever, as shown in Figure 1.

The invention being intended to be pointed out in the claims, is not to be limited to or by details of construction of the particular embodiment thereof illustrated by the drawings or hereinbefore described.

I claim:

1. In combination with a door swingably mounted on its jamb, a device of the character described, comprising: a display element rotatably mounted on the door and having a cam bearing with oppositely disposed helical portions; an element having'a reciprocating movement on the door and engaging in the cam bearing to rotate by said movement the display element; connections between the jamb and the reciprocating element for reciprocating the same by the swinging movement of the door.

2. In combination with a door swingably mounted on its jamb, a device of the character; described, comprising: a. display element rot-atably mounted on the door and having a cam bearing with oppositely disposed helical portions; an element having a reciprocating movement on the door and engaging in the cam bearingto rotate by said movement the display element; connecp tions, including a spring, between the jamb and the reciprocating element for yieldingly reciprocating. the same by the swinging movement of the door.

. 3. In combination with a door swingably mounted on its jamb, a device of the character described, comprising: a display element 'rotatably mounted on the door and having a cam bearingwith oppositely disposed helical portions. and guiding extensions' between such opposite portions; an element having a reciprocating movement on the door and engaging 1n the cam bearing to rotate by said movement the display element; connections between the jamb and the reciprocatmg element for reciprocating the same by the swinging movement of the crumed on the door and connected to the reciprocating element; a leaf springinounted on the jamb and pivotally connected to the lever and adapted to be flexed by the swinging movement of the door.

5. In combination with a door swingably mounted on its jamb, a device of the character described, comprising: a display element rotatably mounted on the door and having a cam bearing with oppositely disposed helical portions; an element having a reciprocating movement on the door and engaging in. the cambearing to rotate by said movement the display element; a lever fulcrumed on the'door and connected to the reciprocating element; a, swingable'member mounted on the jamb and connected to the lever and adapted to be swung by the movement of the door...

In testimony whereof I have hereunto set my hand at Grand Rapids, Michigan, this 15th day of May, 1924.
